The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.
over the past six months I've been doing an experiment where every time I do a zone two workout I'm using the heart rate that it predicts I'm riding to my rpe and then I compare the lactate at the end of that ride to the predicted heart rate from Morpheus to the rpe heart rate and I will say that it tracks pretty darn well better than I would have expected
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
I have recorded every single workout I have ever done for the last year and a half and I record the following I record the heart rate predicted by Morpheus for what my zone 2 is the heart rate I largely end up at by RP and sometimes they're close usually they're quite close sometimes they're quite far
morphia said I should have been at 140 or 139 for Zone 2 I got on the bike and I did not feel great and I sort of said I think Morpheus got it wrong I'm going to ride to this wattage and my heart rate was about 132 and I checked my lactate and it was 1.1 MMO I was nowhere near my limit of where I could have been that day
I have to tell you Joel I I cannot put in words how impressed I am with that system and how remarkably accurate it is at predicting something that is very difficult to predict
the Morpheus app gives you target zones for heart rate every day and if you use the cut off between what it's calling Zone one and zone two that's a pretty good proxy for what your zone two is on that day
it it's called Morpheus Morpheus yeah um so I have no affiliation with or anything like that
